Why Does My FPS Crash When I Move My Mouse in Certain Games?

-

I’m experiencing a frustrating issue where my frame rate drops significantly when I move my mouse in certain games like Dota 2, Dead by Daylight, and Mafia 2. This problem started a few months ago. It’s strange because my FPS is fine when I keep the mouse still, but as soon as I start moving it, the FPS drops to around 10, making the game unplayable. This issue pops up after I’ve been playing for about an hour, and the only way to fix it is by restarting the game, which is a hassle during online matches. I’m running these on an Arch Linux system with an NVIDIA GeForce GTX 1060 and an AMD Ryzen 5 CPU. All my drivers and software are up to date. Any ideas on how to fix this would be greatly appreciated!

Thanks for the tips, but what exactly is the Steam game capture feature? I’m using a physical capture card on a different PC and the issue still happens even when I’m not streaming. Does this fix still apply?

It sounds like you’re dealing with a known Steam bug related to their screen capture feature. The good news is there’s a workaround. You can try modifying the launch options for each affected game by adding `LD_PRELOAD=”” %command%`. This should help bypass the issue and keep your FPS stable even when using your mouse.

Absolutely, it still applies! The Steam game capture feature might be running by default in the background even if you’re not using any capture software. This issue can still affect your gameplay and FPS. Applying the launch command can help resolve the problem regardless of how you capture your gameplay.

If you’re using Steam, this mouse-related FPS drop might be due to their game capture feature causing problems. To troubleshoot, add this command `LD_PRELOAD=”” %command%` to your launch options for problematic games. Remember, you need to set this command individually for each game. Give it a shot and see if it helps!
